The proportion of isolates resistant to penicillin ranged from 13 to 19% over the 10-year period, without evidence of an increasing trend (χ 2 for trend, p = 0.14) (Table 1 ).

In separate multivariable models for patients <15 years versus patients ≥ 15 years of age, mortality was significantly higher among patients < 15 years with penicillin-resistant isolates (adjusted HR 1.22, 95% CI 1.04 to 1.43), while the association did not reach statistical significance among older patients (adjusted HR 1.22, 95% CI 0.96 to 1.56).
